Understanding the Problem
What drum rollers do and why they fail: Drum rollers (also called drum support wheels) support the dryer drum and allow it to spin smoothly. Over time the rubber tires or the wheel bearings wear, causing squealing, thumping, rubbing, increased belt wear, or drum wobble. Replacing worn rollers restores quiet, smooth operation and prevents further damage to the belt and drum. Step-by-step diagnostic and repair steps: 1) Confirm the symptom: With the dryer empty, open the door, spin the drum by hand. Note any roughness, scraping, wobble, or squeal. If you hear squeal or feel rough spots, the rollers are likely worn. 2) Safety first: Unplug the dryer from power. If gas model, turn off the gas supply. Work in a well-lit area and keep track of screws and fasteners. 3) Tools and supplies: Phillips and flat screwdrivers, 1/4" and 5/16" nut drivers, socket set, needle-nose pliers, putty knife, replacement drum roller kit (match to model), high-temp appliance grease (for lubricant), rags. 4) Access the rollers: For most LG front-load dryers including DLG series, remove the top panel (release clips at front with a putty knife or remove rear top screws), then remove the front panel (disconnect door switch harness). Some models require removing the lint filter housing and/or access panel first—refer to your model's service sheet if available. 5) Remove the drum: Slide the drum forward enough to access the rear bulkhead and rollers. If fitted, remove the drive belt from the drum and motor pulley or idler and set the drum aside. 6) Inspect rollers and shafts: With the drum out, manually spin each roller wheel. Look for flat spots, cracked rubber, metal-on-metal noise, or rollers that wobble on their shaft. Check the roller shafts/bushings for excessive play. 7) Remove old rollers: Remove fasteners holding roller shafts or roller mounts (usually 1–2 screws per roller). Pull rollers straight off. Clean the mounting area and remove lint buildup. 8) Install new rollers: Fit new roller wheels onto the shafts or into their housings. Apply a very small amount of high-temp appliance grease to the roller shaft where it contacts the bushing (do not over-grease; avoid grease on tire surfaces). Fasten roller mounts securely but do not over-torque. 9) Reassemble drum: Reinstall the drum, route the belt correctly around the drum and idler/motor pulley (ensure belt ribbed side matches drum grooves), reattach front panel and top panel, reconnect any harnesses. 10) Test run: Reconnect power, run the dryer empty on a normal cycle and listen. The drum should rotate smoothly without squeal or thump. Watch for any wobble. 11) Final check: After a short run, turn off power, re-check fasteners and that the belt is seated correctly. Safety note: Always disconnect electrical power before servicing. If you are not comfortable performing disassembly or dealing with gas connections, hire a qualified technician. Confirm replacement part compatibility using the dryer’s model and serial number before ordering.
Common Symptoms
Loud squealing or grinding during spin, rhythmic thumping or knocking as the drum turns, visible drum wobble, accelerated belt wear or frequent belt breakage, burning rubber smell from overheating rollers.
Common Causes
- Worn roller rubber tires that develop flat spots
- Seized or dry bearings inside the roller
- Broken roller mounts or cracked housing
- Lint buildup and lack of lubrication causing drag

Helpful Repair Tip
To confirm rollers are bad, remove the belt and spin each roller by hand; a worn roller will feel gritty, bind, wobble, or make noise. Also check for drum wobble with the belt off—excessive side-to-side movement indicates worn rollers.
Frequently Asked Questions
How long does it take to replace drum rollers on a DLG5988W?
For a competent DIYer with the right tools and a correct roller kit, expect 45–90 minutes. If you need to source parts or are unfamiliar with disassembly, allow additional time or hire a technician.
Can I lubricate old rollers instead of replacing them?
No — lubricating worn rollers is only a temporary fix and not recommended. Worn rubber tires or play in the bearing require replacement. Use a small amount of high-temp appliance grease on new roller shafts during installation; do not apply grease to the roller tire or the drum surface.
